Wow. I've struggled with #1-9 at various times over the last year since I've had the Mirena removed. I started having problems after it had been in for 1 1/2 years. I had it placed when my baby was 10 months old, however, so a little later than you. I had a brain and optic nerve MRI. Both normal. I feel better after a year since having it out, but still struggling mostly with tremors, weakness in my arms and legs (worse on the rt. side), heavy legs, vision distortio, slight dizziness (it was vertigo at first so this much better and doesn't bother me too much), occasional twitching (most recently my eye lid twitching horribly for a month. Now it has stopped.
Get the IUD out and start recovering! Glad you've joined us!
